摘要：
The asymmetric unit of the title compound, [Pt(C25H22P2)(C27 H26P2)]Br2 or [Pt(dppm)(dppp)]Br2, where dppm is bis(diphenylphosphino)methane and dppp is 1,3-bis(diphenylphosphino)propane, consists of a discrete [Pt(dppm)(dppp)]2+ cation and two Br- anions at van der Waals distances. This is the first reported platinum(II) complex containing both dppm and dppp ligands. Noticeable features are that the coordination of platinum by the differing dppm and dppp ligands produces a distorted coordination geometry with differing ligand bite angles (and to a lesser extent bond distances), and that the strain induced by the formation of the four-membered dppm chelate ring has a marked effect upon the bond angles at the P atoms of this ligand.
